Heavy metals and nutritional composition of some naturally growing aquatic macrophytes of Northern Egyptian Lakes
Aquatic plants are unchangeable biological filters and they carry out purification of the water bodies therefore, the determination of element compositions in these plants is essential for understanding their nutritive importance. Aquatic macrophytes are known as good indicators of heavy metal contamination in aquatic ecosystems and they act as biological filters by accumulating heavy metals […]
Effects of tropical legume cover crops on soil quality at dryland farming area in Bali, Indonesia
Two field experiments were conducted to study the effects of tropical legume cover crops on soil quality in dryland farming areas at Angantaka village, Badung regency, Bali Province of Indonesia from June to November 2013. In the first experiment, three tropical legume cover crops (LCC) (Centrosema pubescens L.(Cp), Mucuna pruriens L.(Mp) and Pueraria javanica L. […]
Checklist of the opisthobranchs (Heterobranchia: Gastropoda) along the Iranian coasts of the Gulf of Oman
This is the first paper describing the heterobranch fauna of the coasts of Iran. A total of 25 species belonging to 14 families is recorded from the Iranian coasts of the Gulf of Oman. Except for Chromodoris annulata, the remainder are all new records for the area. The families Chromodorididae and Aplysiidae have the highest […]
Influence of soil physicochemical parameters on the abundance of Paracoelophrya polymorphus (Ciliophora: Radiophryidae) commensal of earthworms (Annelida: Glossoscolecidae) collected in Bambui (North-West Cameroon)
Earthworms of the genus Alma nilotica belonging to the family Glossoscolecidae, lodges an abundant fauna of astomatous ciliates in its digestive tract. Each species is located in a well-defined portion of the gut and the reasons for this stratification still remain unclear. In order to assess the influence of physico-chemicals parameters of the soil on […]

Effect of some soil properties on distribution of Ceratocarpus arenarius and Aristida funiculata in Mardan, Kashan Rangelands
In order to sustainable use of rangelands, it is necessary to recognize water, soil, and vegetation cover and analyze their relationships. Physical and chemical properties of soil are effective in distribution of plant species in local area. To determine the effects of some soil properties on species distribution of Ceratocarpus arenarius and Aristida funiculata in […]
Growth, gas exchanges and accumulation of inorganic matter of Populus nigra L. in responses to treated wastewater
Tunisia has made considerable efforts to solve major environmental problems. Reforestation of vast marginal spaces with appropriate species, such as poplar, is one of the economic and environmental challenges (I-488). The fast-growingof this rupicolous species has a high specific versatility in its use. However, its need for water will limit their use in reforestation in […]
Evaluation of systematic random sampling method for quantitative estimation of rare and thick trees in Caspian Forests. (Case study: Kheyroud-Kenar, Naushahr, Iran)
Knowledge and recognition of existence or absence and real type and amount of rare and thick trees in natural stands for studying silviculture, forest management, biodiversity, etc. can be useful. Recognition of number of trees distribution in different diametric classes is necessary not only in the study of progress circumstance of forest stand but also […]
